I’m going to mark this as completed so you can get your votes back – note that Matthew Johnson has released a VS 2012 color theme editor as you requested (link below) – I know it doesn’t have everything you requested in this idea, but hopefully this helps to address your feedback.

A word on Metro UI Style
At first I thought the metro tiles look like a cheap approach of "coder drawn placeholders" like you would use for prototyping. Furthermore I thought MS knows what they are doing and it would just a matter of time to get used to it. Well, as time passed by - compared to Apples UI design - it still looks ugly to me on W7 Phone as well as on W8. I never would have thought that MS will try to push a bad UI design by all available means. And now, that I had to experience the defaced UI of VS 11, I bet, that this comprehensive "forced fit" of the Metro UI marketing will lead to no good. According to Steve Ballmer this “most important year” might be - at least in my opinion - the decline of Microsoft on a variety of products and/or markets. With the lack of color and therefor of information, I can not use VS 2012 in production. Dispite of the caps, the visual seperation of elements, the strange icons and lots of other things are far beyond the pale. To payfor this products, would be a fraud, to provide it for free, would be insulting, to use it, is definitly an imposition. Sorry Microsoft, you have reached an impasse.
